(1 point) A tank contains 2780 L of pure water. Solution that contains 0.01 kg of sugar per liter enters the tank at the rate 4 L/min, and is thoroughly mixed into it. The new solution drains out of the tank at the same rate.
(a) How much sugar is in the tank at the begining?
y(0)= (kg)

(b) Find the amount of sugar after t minutes.
y(t)= (kg)

(c) As t becomes large, what value is y(t)y(t) approaching ? In other words, calculate the following limit. limt→∞y(t)= (kg)
